as_to_org_mapping-20101019 2010-10-19 2010-10-19 9.25M This dataset provides a mapping from ASes to organizations, i.e., identifies which ASes belong to which organizations. We determined the mapping by automatic clustering methods. The general idea of the methods is to cluster ASes by their attributes found in WHOIS databases obtained from five Regional Internet Registries (RIR). README
as_to_org_mapping_inferred_truth-20110901 2011-09-01 2011-09-01 252.77K This dataset provides a mapping from ASes to organizations, i.e., identifies which ASes belong to which organizations. We determined the mapping by manual inspection of RIR whois information, using AS names and external information (company web pages, wikipedia, etc.) to infer a feasible ground truth. This dataset comprises 109 organizations and their 4019 ASes in total. README
as_to_org_mapping_inferred_truth-20100507 2010-05-07 2010-05-07 38.85K This dataset identified the ASes beloging to 9 large Internet organizations.

as_to_org_mapping_subsidiary_linkage-20101019 2010-10-19 2010-12-31 2.52G This dataset provides a linking between ASes and company subsidiaries. It is derived from WHOIS database and Form 10-K filings. The linking is useful to associate ASes that belong to different subsidiaries of the same organization. We determined the links by automatic record linkage algorithms and followed by manual verification and pruning. The general idea is to compare how similar the name of an AS is to the name of a subsidiary. Due to the inaccuracy of automatic linkage, we then manually verify and prune the links for selected most important organizations. README

It includes only Mirai-identified TCP SYNs sent to ports 23 and 2323; other traffic is removed. Through 2016-11-20, we observe only traffic to one IP address (130.152.184.2). From 2016-11-20 onward it adds traffic to 192.228.79.0/24. README

UniformAttack_Traces_Generated20070821-20041202 2004-12-02 2004-12-03 2.69G This trace set contains 16 trace pairs created in August 2007 using background trace data recorded in December 2004. Each trace pair has the same uniform attack, and different background traffic. The background traffic bitrates are 196 Mbps and 320 Mbps, from the D12_02T01_56 and D12_02T15_56 traces, respectively. The uniform attack increases exponentially from 1 Mbps to 250 Mbps. The two streams were merged with the uniform attacks using the stream_merger application. The scripts and instructions are available in http://www.isi.edu/ant/software as DAG trace generator. This dataset supersedes and corrects UniformAttack_traces-20070115 http://wiki.isi.edu/predict/index.php/LANDER:UniformAttack_traces-20070115 README

geoloc_university_ground_truth-20151001 2015-10-01 2015-10-02 1.65M This dataset contains latency measurements and location information for 85 /24 blocks that belong to universities around the world. The IP addresses of each block are believed to be closely co-located. The measurements are leveraged from the IP Geolocation datasets: InternetTopologyData/IP_Address_Geolocation_Data provided by the USC/LANDER project ( http://www.isi.edu/ant/lander ). The location information is obtained from Google Geocode API and MaxMind GeoLite City database. The dataset also provides artificial dual-location blocks made by merging IP addresses from two different single location /24 blocks. The two merged blocks are VP-compatible (probed by the same set of of VPs). The distance between the combined blocks varies across the artificial blocks. This dataset can be useful for geolocation and IP blocks co-locality research. README

internet_address_history_standing_w-20110913 2011-09-13 2020-01-01 UNKN This is a standing dataset, which means that applying for it, researchers effectively apply for the most recent IPv4 census response history dataset, and for all subsequent ones within 1 year. The researchers will be distributed newer datasets of the same category, as they become available. Please note, that this standing request applies only to histories obtained from one particular location. This standing dataset only covers censuses from isi.edu in Marina del Rey, California. For an example of a dataset distributed via this standing request, please see: internet_address_history_it52w-20130102 README

internet_address_survey_tcp1-20031120 2003-11-20 2004-03-19 472.74M To collect this data, an Internet-wide IP address sweep was conducted. Every IP address in the ranges allocated by IANA was pinged at least 5 times by sending TCP SYN (other flags were experimeted with) packets to it, before giving up. High unused destination port was used. If the response (typically TCP RST) came, its IP address was recorded in this data-set. In all, approximately 2.5 billion distinct IP addresses were probed during this experiment. README
